Conclusions Our findings therefore identify the miR-17-92 cluster as a functionally determining family of miRNAs in CSCs, and highlight the putative potential of 

In vitro, the miR-17–92 cluster promotes oligodendrogenesis, neurogenesis, and axonal outgrowth. We, therefore, investigated whether the miR-17–92 cluster–enriched exosomes harvested from MSCs transfected with an miR-17–92 cluster plasmid enhance neurological recovery compared with control MSC-derived exosomes. The miR-17-92 cluster (encoding miR-17, -18a, -19a/b, -20a, and miR-92a) is highly expressed in tumor cells and is up-regulated by ischemia. Whereas miR-92a was recently identified as negative regulator of angiogenesis, the specific functions of the other members of the cluster are less clear.

In the present study, by specific ablation of this cluster in Adipogenesis involves cell proliferation and differentiation, both of which have been shown to be regulated by micro (mi)RNA. During mouse preadipocyte 3T3L1 cell differentiation, we found that miR-17-92, a miRNA cluster that promotes cell proliferation in various cancers, was significantly up-regulated at the clonal expansion stage of adipocyte differentiation. miRNA-17–92 cluster plays a role in Y79 cell proliferation. Invasion— A matrigel invasion assay was performed on the Y79 cells after 48 h of treatment with antagomirs. Abstract: The human polycistronic miRNA cluster miR-17-92 is frequently overexpressed in hematopoietic malignancies and cancers. Its transcription is in part controlled by an E2F-regulated host gene promoter.

tant miRNA of the miR-17-92 cluster in c-Myc-induced lymphomagenesis, both groups studied the mRNA tar-gets of miR-19. Mu et al. (2009) analyzed changes in gene expression in a lymphoma cell line derived from a mouse homozygous for the inducible deletion of the miR-17-92 cluster and heterozygous for Em-Myc. They found 568

This study aimed to explore Interestingly, deletion or overexpression of miR-17- 92 cluster in keratinocytes, or deletion of miR-17-92 in T cells did not significantly affect IMQ-induced psoriasis- like dermatitis develop-ment in the mutant mice compared with wild-type littermates. Thus, miRNA miR-17- 92 cluster Many RNAs are processed into biologically active transcripts, the aberrant expression of which can contribute to disease phenotypes.

The miR-17∼92 cluster is frequently amplified or overexpressed in human cancers RESEARCH PAPER: miR-19 is a key oncogenic component of mir-17- 92.

Thus, miRNA miR-17- 92 cluster Many RNAs are processed into biologically active transcripts, the aberrant expression of which can contribute to disease phenotypes. For example, the primary microRNA-17-92 (pri-miR-17-92) cluster contains six microRNAs (miRNAs) that collectively act in several disease settings. Herein, we used sequence-based design of structure-specific ligands to target a common structure in the Dicer Members of the miRNA gene cluster can coordinate the regulation of certain processes or play a similar role in the same biological process, ensuring biological activity occurs in a normal and orderly fashion. miR-17-92 encodes a miRNA precursor and produces 7 mature miRNA molecules that belong to 4 miRNA families.

We successfully integrated exogenous shRNAs at the porcine miRNA-17-92 (pmiR-17-92) cluster via a CRISPR/Cas9-mediated knock-in strategy. We dissected the role of individual miRNA components of the miR-17-92 cluster in thyroid differentiation, especially the impact on NIS levels, and observed that while some miRNAs such as miR-17-5p, miR-19a/b, and miR-92 may inhibit NIS expression, others such as miR-20a-5p do not modulate NIS levels. 2013-11-11 · MiR-17/92 is one of the best-known miRNA clusters.

MiR-17-92 cluster is an oncogenic miRNA cluster that is implicated in several cancers, although its role in hepatocarcinogenesis has not been clearly defined. In this study, we show that the miR-17-92 cluster is highly expressed in human hepatocellular carcinoma (HCC) tissues compared to the non-tumorous liver tissues by RT-PCR and in situ hybridization analyses.

Conditional KO of the miR‐17‐92 cluster in NSCs impairs adult neurogenesis. The miR‐17‐92 cluster incorporates a family composed of 6 miRNAs (miR‐17, miR‐18a, miR‐19a, miR‐20a, miR‐19b‐1, and miR‐92a), which is highly conserved in humans and rodents (Fig. 1A).

An abnormal functioning of which can induce the GNP tumours typical of Medullablastoma. This hypothesis was arrived at by taking miRNA expression profiles of … Because of its strong oncogenic activity, the miR-17-92 cluster was also named as oncomiR-1. Thus, here we asked whether the placement of miRNAs in an miRNA cluster contributes to determining the miRNA expression patterns by investigating the relationship between expression and placement of miRNAs in the miR-17-92 cluster.
